Hmm… I am wondering how the tail rotor servo arm broke. From what you saw, is there any explanation for this? If you want a somewhat beefier servo arm I suggest the Dubro Super Strength Servo Arms:

They carry these at my LHS on the Dubro rack and are significantly stronger than the tiny stock horns. Just make sure you get the right ones for your servo brand. After figuring out the correct arm length, hole size, ect. I usually trim away all the extra arms or excess material to save a gram or two.
Darth has you covered on the crash repairs. I would recommend the steel rod over wood for tapping out your tail boom dents. I used a steel one for the first time last night and was very impressed with the nearly new results. You might also want to check out the mesh between the main shaft bevel gear and the tail rotor drive wire bevel gear. The tail boom has a tendency to shift around a bit when you have a “quick” landing. Just give everything the once over.
On the radio I would again agree with Darth. I have a minimally fancy computer radio that I could use if I ever decided to get some high dollar non bounceable helicopter, but I don’t see that happening any time soon. Truth be told I don’t use a single one of the “heli” features on the radio, though I find the adjustable servo travel, dual rates, and remote gyro mode selection to be very convenient. In fact Darth raises a good point. Make sure you are not using Idle Up, Throttle Hold, Hover Pitch, or any other heli mixing functions as these are not intended for use with your particular setup. Revolution Mixing can be used with a standard or “rate” gyro, but you must not use this feature if you use your gyro in a Heading Hold mode. Other than that, Hovering Throttle can be pretty useful to dial in the throttle curve the way you want it. You usually want to set this up so that your heli hovers at 1/2 throttle. I imagine your radio’s documentation has some pretty good instructions on how to setup or disable these features. If you have any specific questions on how these features relate to your heli, feel free to post them up here and let us take a crack at them.
For what it is worth,
